Complementary SPAMM (or CSPAMM) is a popular approach to acquire tagged datasets due to its ability to provide dark blood contrast, and permit faster segmentation of the cardiac cine data. However, since CSPAMM requires two separate acquisitions, misregistration between the two acquisitions can frequently arise, affecting the accuracy of any wall function quantification performed subsequent to the segmentation. We present an alternative approach, VaFA, for obtaining SPAMM data with dark blood contrast in a single acquisition. This approach eliminates the issue of misregistration, and due to the dark blood contrast, can provide similar segmentation benefits as CSPAMM.
